This course presents five case study situations in which pre-restorative orthodontics contributed great benefit to restorative esthetics.

1. Determine which restorative situations can benefit from vertical orthodontic repositioning.
2. Describe treatment options for correcting a "gummy smile."
3. Explain the importance of allowing sufficient time for the teeth to stabilize after completion of the intrusion/extrusion process.
4. Identify the appropriate treatment for correcting discrepancies in gingival levels.

Throughout the 1990s, esthetic dentistry became a prominent part of the treatment protocol of most dentists. Patients have become more conscious of the benefits of a beautiful smile and are willing to invest time and money to improve the appearance of their teeth. Many of these patients can be treated with routine restorative procedures (crowns, composites, laminates) to achieve the desired results. However, some patients have problems with tooth position creating significant discrepancies in gingival levels, which can compromise the esthetic result of restorative dentistry. Pre-restorative orthodontic therapy can often resolve these tooth position problems and enhance the esthetic restoration. This course describes the indications, methods, and results achieved when orthodontics preceded restorative dentistry in the treatment of various esthetic challenges.
